Underexposure Problems

Does underexposure causes problems with Raw files? And, if so, is this further affected by a smaller digital camera?

  Underexposure can often be the source of digital noise in many digital cameras and brands. If you over-simplify this to consider the effect under-exposure has on film, you will have similar difficulties. One of the keys is to be aware of in-camera meter readings, and know when your exposures are not going to be their best. At that point you can either accept the risk, or make adjustments (e.g., using a faster lens, changing the ISO, etc.).
Underexposure is not only an issue with RAW, it will likely cause additional noise in other file formats, and in many cameras - more and less depending on the brand of camera and the extremes of exposure.
